since I have just found the solution about AppleSMBus , there are two kexts : AppleSMBusController and AppleSMBusPCI. After SBus dsdt patching , if you make an SMBusPCI_injector.kect , with your vendor and device id , put it in /Extra/Extensions/ , then the two kexts are loaded.




P.S: Anyone can help for my memories issue. I also tried Lizard among others , without success.
